Indian consumers are increasingly sourcing credit, loans, and savings from different providers rather than a single bank. This shift, driven by digital platforms and fintechs, forces banks to invest heavily in Super Apps and niche products to retain customers. For investors, this trend creates risks for low-cost deposit growth and may increase customer acquisition costs across the banking sector.
The traditional model where an Indian household kept all its money, loans, and credit cards with a single bank is fading. Instead, consumers are increasingly "unbundling" their financial lives. They might hold a salary account with one lender, use a different bank for a home loan, and rely on a fintech app for credit cards and daily payments. This shift is driven by digital tools, such as instant KYC and the Account Aggregator framework, which make it easier for customers to compare rates and switch providers without visiting a branch.
Impact on Bank Funding and Margins
The biggest risk for banks in this shift involves low-cost deposits, known as CASA (Current Account and Savings Account). Historically, banks counted on primary account holders to keep funds in savings accounts, which provide cheap capital for lending. If a customer uses a bank solely for a specific credit card or loan but keeps their primary savings elsewhere, the bank loses access to that low-cost funding. This can increase the overall cost of funds and put pressure on Net Interest Margins (NIMs), a key measure of a bank's profitability.
The 'Super App' Strategy
To fight this unbundling, major Indian lenders like HDFC Bank, ICICI Bank, and Axis Bank are investing heavily in "Super Apps." These applications aim to consolidate various financial services—from investments and insurance to loans—in one digital ecosystem. The goal is to retain the customer within the bank’s platform, increasing the "stickiness" of the relationship and preventing customers from moving to fintech competitors for specific services.
However, this defensive strategy comes with its own costs. Banks are seeing higher technology spending and elevated Customer Acquisition Costs (CAC). Lenders are also launching niche products, such as co-branded credit cards with major retailers, to capture specific consumer spending segments that were previously guaranteed under the old model.
Regulatory and Market Context
The Reserve Bank of India (RBI) has facilitated this change through the Account Aggregator system, which allows customers to share their financial data securely across institutions. While this promotes competition and provides consumers with better choices, it also levels the playing field for newer, digital-only lenders.
For investors, the key monitorables moving forward will include the CASA ratio in quarterly financial results and the efficiency of digital spending. A consistently falling CASA ratio or rising acquisition costs could indicate that a bank is struggling to maintain customer loyalty in this highly competitive, modular financial environment.
